Specification of Letters Patent.

Patented Apr. 1, 1913.

Divided and this application filed December 14, 1910. Serial No.597,382.

To all whom it may concern:

Be it known that I, ED\VARD W. ROBINSON, a citizen of the United States,residing in Savannah, Chatham county, State of Georgia, have inventedcertain Improvements in Barrels, (the same being a division of myapplication, Serial No. 591,505, filed November 9, 1910,) of which thefollowing is a specification.

My invention relates to barrels composed of staves interwoven withproperly spaced pairs of wires which take the place of the usual hoopsfor retaining the staves in proper relation to one another, and myinvention relates particularly to a barrel of this type intended for thestorage and transortation of powdered or granular material andtechnically known as a slack barrel in contradistinction to what istechnically known as a tight barrel, which is intended for the storageand transportation of liquids.

The object of my present invention is to provide a strong and durablehead for a barrel of this type, which head can be readily applied orremoved, and which, when in position, will effectively back up orreinforce the ends of the staves. This object I attain in the mannerhereinafter set forth, reference being had to the accompanying drawings,in which Figure 1 is a side elevation of part of a barrel constructed inaccordance with my present invention; Fig. 2 is a vertical section ofone end of the barrel withv the head inserted therein; Fig. 3 is asectional view of the head as it appears when detached from the barrel;Fig. 4 is a top view of the head showing the parts of the same in theposition assumed by them when the head is inserted in the barrel, as inFig. 2; Fig. 5 is a top view of the head showing the parts in theposition assumed by them when the head is removed from the barrel, as inFig. 3, and Fig. 6 is a sectional plan view of part of the barrel, onthe line a-a, Fig. 1. Fig. 6 is on a larger scale than Figs. 1 to 5,inelusive.

The barrel is composed of staves 1 which are preferably narrower at theends than at the center so that when the staves are drawn together untiltheir edges meet, the barrel will present the desired bilged form, theedges of the staves being beveled to insure theclose fitting of thesame. The staves are confined in position by as many pairs of wires 2 asit may be desired to employ, each stave being inserted between the wiresof each pair and the latter being twisted together between the staveswhich are mortised at each edge, as shown at 3 in Fig. 6, in order toreceive these twisted portions of the wires.

The head of the barrel is composed of two laterally separable members aand 5, whose central or meeting edges are rabbeted, as shown by dottedlines in Figs. 2, 3, 4 and 5, and whose peripheral portions are grooved,as shown at 6, in Fig. 3. The meeting portions of the members 4 and 5 ofthe barrel head are recessed, as shown at 7, for the reception of a cam9 which is secured to or forms part of a batten 10 on the outside of thehead and a plate 11 on the inside of the head, whereby said camstructure is vertically confined to the members of the head but is freeto turn thereon. When the cam is turned so that itsmaj or axis isparallel with the joint between the two members of the head, as shown inFigs. 3 and 5, said members of the head can approach eachother so thattheir adjoining edges will meet and the diameter of the head is therebycontracted to such an extent that it can be readily introduced into orremoved from the barrel. When, however, the cam 9 is turned to suchposition that its major axis is at right angles to the joint between thetwo members of the head, as shown in Figs. 2 and 4, said members areformed apart and the grooved periphery of the head is caused to engagewith the inner of the pair of wires with which the end portions of thestaves are interwoven, the head being thereby securely locked to thebarrel so as to resist either pressure from the outside tending to forceit into the barrel or pressure from the inside tending to force it outof the barrel.

By preference the staves are concave on their inner faces as shown inFig. (3, and the central portion of each inner wire, bridging thisconcave, will, therefore, occupy a position some distance inward fromthe inner face of the stave and will provide a better hold for thegrooved periphery of the barrel head than it would if it laid snuglyagainst the inner side of the stave. The peripheral portion of thebarrel head is of such thickness as to be flush with theends of thestaves and thus provides backing or support for said staves, up to theends of the latter, as shown in Fig. 2, but the outer face of the headis recessed, up to a point" adjacent to the periphery, as also shown inFig; 2, the purpose of this recess being to lighten the head and toprevent the camoperating batten 10 from projecting beyond the head. Bypreference, the batten occupies a position at right angles to the jointbetween the members of the head when the latter are contracted, as shownin Figs. 3 and 5, andparallel with said joint when the members areexpanded, as shown in Figs. 2 and 4, the batten then serving to closethe gap between the outer portions of the rabbeted oint and thuspreventing any leakage which might otherwise take place at said jointThis,however, is simply in the nature of an added precaution, since therabbeted portions of the joint are intended to overlap sufliciently toprevent leakage un derrnormal circumstances.

The batten 10,,on the outside'of the head, and. the plate, 11, on theinside of the head, effectually prevent leakage through the re cesses7inthe opposite members of the head when said-members are expanded, Whenit is desired to seal the barrel, such sealing can be readily effectedby securing the batten in the-locking position'shown in Figs. 2 and 4 bydriving: a nail or screw through the battenandinto one of the members ofthe head and then applying a seal of any desired character to the head#01 said nail or screw, or, suitable staples, one on the batten and theother on one of the head members, may

be connected by a wire whose ends are secured'by the usual lead seal, orother equivalent means of sealing the batten in the locking position sothat it cannot be moved from such locking position without breaking theseal, may be adopted.

I claim:

1. The combination of a barrel composed of close fitting stavesinterwoven with pairs of wires to form a permanent bilge, and a of wiresto form a permanent bilge, and a head composed of laterally separablemembers having their peripheral portions grooved for engaging the innerwire of the pair at the end of the barrel, and means for maintainingsaid members of the head in the separated position and in engagementwith the wire, said head having a thickened.

integral peripheral portion, whereby its outer face is flush with theends of the staves.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.

EDWARD W'. ROBINSON.
